The device as shown inthese patents and application are ideal for' thepurpose, butA the present invention aims to provide certain improvementswhich permit greater ease in manufacturing and also better operation.

Having regard to the foregoing,the present invention contemplates anatomizer of the following construction. It includes a body formed withfirst and second spaced-apart chambers each extending fro'm one end ofthe body to adjacent the other and a transverse passageway leading lfromthe chambers toa dispensing `outlet on a face of the body. The firstchamber extends vthe first chamber. A first tubeis located in thetransverse passageway and extends from a point between the two chambersto the outlet forming an air passage between the secondk chamber and theoutlet. A second tube larger than the first tube is located in thepassageway and surrounds the rst tube. Preferably the tubes arecylindrical and concentric. VThe second tube extends from a pointbetween therst chamber and the outlet so as to form between it and thefirst tube a liquid passage leading from the first chamber to theoutlet. The ends of the two tubes are coextensive and form therebetweenaliquid outlet, while the rst tube'forms an air inlet concentric with theliquid outlet. The inner end of the second tube forms between it and therst tube a liquid inlet having access at all sides of the rst tube tothe chamber. Adjustable means is provided for controlling the liquidoutlet.` This means prefer-ably include a cap having Ya skirt threadablyengaging the outside of the second tube. The cap includes an openingadapted to register with the above-mentioned air opening. The insideofthe cap is provided with a washer adapted t0 overlie the ends ofthe-first and `second tubes and so the liquid outlet formedtherebetween. The second chamber includes a pump for forcing air throughthe air communication and outlet so as to aspirate liquid from theliquid communication. f

In one embodiment of the invention, the first chamber has an opening onthe surface of the body at the endl remote from the transversepassageway and this opening is provided with a fremovable closure. Inanother embodiment yof the invention the rst chamber has an opening onthe surface of the body at' the end nearest the transverse passagewayand this opening is provided with a removable closure.

According to a further embodiment ofthe invention there is a iirsttubular member mounted within the transverse passageway and extendingthrough the outlet end thereof to 'a' point beyond said first chamber.This 4tube has a xedcap on its outer extremity having an orice thereinconstituting a dispensing opening. A `passage-forming member isadjustably mounted within the passageway, for example by the passagewaybeing tapped and the passage-forming member being threaded, this memberextending from a yp Oint adjacent the cap to a point on the oppositeface ofthe body. l i L This member is provided with an opening extendingfrom the outlet end to a point beyond the second passageway and isprovided with a portion of reduced diameter extending from thev endadjacent the opening to a point normally beyond the second passageway.Thetubeand Y tto bring the head against the cap for sealing the liquidopening or to adjust the clearance for dispensing. The member is formedwith ano-pening leading from its bore to thesecond chamber. The secondchamber containsthe air pump.

According t0v a modification of this structure,

' the passage-forming member includes an annular outside Washer adjacentthe vend remote from the outlet to prevent escape of liquidY from saidsecy ond chamber, In accordance with a still further renement of theinvention the outlet end of the passage-forming member is provided witha perforated nose of resilientmaterial 'adapted to seat on the nozzle ofthe cap and a central vent tube projecting beyond its end.

Detailed description Having thus generally described the nature of theinvention, it will be described in more detail by reference to theaccompanying drawings illustrating an atomizer according to preferredembodiments, and in which:

Figure 9 is a vertical fragmentary cross section showing a modificationof the nozzle structure of Figure 8.

Figure 10 is a transverse vertical cross section of the nozzle structureof the atomizer of the previous figure.

Referring more particularly to the drawings, Figure 1 shows onepreferred form of atomizer according to this invention. In thispreferred form the body of the atomizer is made up of a unitary block ofmaterial for example, metal, say an aluminum alloy, which is drilled toform a pair of chambers l5 and 20, and a transverse passage 25. Thechamber is connected to the agonal face of the body. An outer sleeve '40is mounted in the passage 'concentrica1ly with the sleeve 26. There isformed between the inner and outer sleeves 26 and 4D a passage 42. Thesleeves 4B and 26 have co-extensive ends 4| and 29 respectively. The endof the inner Sleeve 26 is provided with a vent tube 45 which projectsbeyond the end of the sleeve 26. Mounted on the en d of the sleevepreferably by screw threading is a cap which has a side skirt 52 whichengages the sleeve 4B, and a cap portion 54. The cap portion 54 isprovided with an opening 55 forming the dispensing opening of thenozzle; A washer 6|! is mounted within the cap 5l). The washer isprovided with a centrally-arranged opening 6| registering `with theopening 55 in the cap 5B. The rear end or' the transverse channel 25 isprovided with a plug 5l'. A suitable closure 'l0 is provided in thechamber I5 anda pump 1| is provided inthe chamber 20.

Operation In operation the body of the atomizer is inverted from theposition shown in the drawings and the plunger is reciprocated whichforces air through the channel 25 and out through the air vent 55. Thepassage of air from this air vent and the opening 4| aspirates perfumefrom the chamber |5 and then out through the passageways between thesleeves 26 and 40 and out between the sleeve 26 and washer 4], then outthrough the opening in the cap.

As will be noted, the extension of the chamber I5 to above the tube 2Band the starting of the tube 40 within the chamber l5 permits readyaccess to the uid of the passage between the members 26 and 4U. When thebody of the atomizer is inverted, the fluid tends to feed by gravitythrough the fluicLpassageway and is readily aspirated from thedispensing opening by air forced from the air channel.

First alternative structure In the alternative structure shown in Figure4 the numbers of the respective parts are'similar with the exceptionthat they have been raised by one hundred. The structure of the atomizeris similar with the exception that there is no recess or diagonalportion 30 on the body and the chamber H5 is of substantially the samediameter throughout its length. The portion of the chamber |15 extendingabove the sleeve |28 is of the same diameter as thel lower portion ofthe chamber.

The operation of this form of the' device is similar to that of Figure1.

Second alternative structure In the alternative form illustrated inFigure 5 two hundred has been added to the numbers of each of the partsand the parts are similar. This form diiers from that of Figure 2 inthat the closure 210 for the chamber 2I5 is at the top of the atomizerinstead of at the bottom, the chamber 2|5 having been formed by drillingthe body from the top instead of the bottom. The operation is the sameas in the previous gures.

Third alternative form The form of the device illustrated in Figures 6through 9 is somewhat different although the principle of operation isthe same. In the transverse passage there is mounted a xed cap member345 provided with a dispensing opening 34|. In the transverse passagewhich is tappedthere is mounted a threaded tube 32-6. This tube isprovided with a narrow portion 328 which forms between itself and thecap 34| a perfume channel leading from the perfume chamber 3|5 to theoutlet inthe cap 34|. The threaded tube 32B is provided with a knurledhead 355 whereby the tube can be turned and thus moved forward orbackward in respect of the cap 34|. In this manner the washer on the endof the tube is brought into contact with the cap or retracted fromcontact with the cap, thus either closing .oil the perfume passage orleaving a passage of adjustable size as the case may be.

The tube 326 is provided with an opening-355 which is adapted toregister with the opening 327 leading from the air chamber to the insideof the tube 326. The cap member 345 is provided with an opening 31|)leading from the chamber 3|5 so that liquid can run from the chamber 3I5into the passage formed between the cap member 345 and narrow portion328 of the passage-forming member.

The operation in dispensing is similar to the device of the otherfigures.

Other forms In Figure 8 is illustrated aslightly different form of tubeinsertable in the transverse channel of the atomizer. The internalopening in the tube is drilled from the front and there is an insertbushing 480 which carries the air vent. A rubber safety joint or sleeve428 may be located in an annular groove in the wall of the tube adjacentto the head. The purpose of this sleeve is to prevent leakage of airfrom the pump.

Figure 9 shows an alternative form of nozzle capable of being usedparticularly with the form of the invention shown in Figure 8. Figure 9shows a variation of the structure shown in Figure 8. The end of thepassage-forming member is provided with an insert 58|) which carries thevent tube 581. Mounted on the vent tube and flush against thepassage-forming member is a washer 585 of resilient material adapted toseat against the inside of a cap like the cap 345 of Figure 7.

Figure 10 is a transverse vertical cross section through a nozzle likethat of Figure 8.
